i TREAIDLE OPERATING MECHANISM FOR STAMPS AND THE LIKE.

To all whom it may Concern:

Be it known that I, ADAM WILSON, a subject of the King of England, residing at Hanwell, London, England, have invented a certain new and useful Treadle Operating Mechanism for Stamps and the like; and I do hereby declare the following to be a full, clear, and exactdescription ofthe'invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1 I

This invention relates to a new or improved method and means for operating hand numbering, stamping, dating .or any such machines or stamps whereby the work is done better, much more quickly and in perfect register.

The invention consists generally in' pro.- viding an apparatus comprising a slide adapted to'be operated vertically by means of a treadle, which slide is provided with means for attaching the hand numbering or like stamp or stamps thereto so that the stamp or stamps may be brought down on to the work while both hands ofthe operator are left free for manipulating the pages of the book or the like being stamped.

In order thatmy said invention may be clearly understood I will the same with reference to the drawing accompanying this specification which shows one method of constructing an apparatus according to such invention for the the operation of a single hand stamp.

Figure 1 shows front elevation of the device, the hand stamp not being in position; Fig. 2 shows side elevation of same with the hand stamp in position; Fig. 3 shows a plan; Fig. 4: shows a detail hereinafter referred to.

The same letters of reference are employed to denote the same parts in all the views. a is an upright standard or stand preferably formed from a metal casting which is bolted or otherwise secured. to a bench or table, holes being provided in the base through which screws or bolts are passed for that purpose.

7) is a projecting bracket formed with the main casting, located about midway up the back thereof, to which bracket is attached by a suitable screw an upright rod 0.

[it the front of the stand a are screwed suitable strips (Z forming an overhanging guideway in which is adapted to work a Specification of Letters Patent;

slide 6 formed of a bar or strip. This bar or the top at right angles forming an arm 7', which is provided witha hole 9 through which the rod 0 passes.

is a spiral compression spring surroundends'of which bear upon the bracket 6 and the under side of the arm f insuch a manner as to push the slide 6 normally upward. The lower portion of the bar or strip 6 is bent at right angles to form an arm is, recesses or notches 11?, being formed for the reception of the edges of the strips (2.

The arm is some length tie n. v

p is a slot formedatthe end of the armJc for thereception of the hand. numbering machine or'the like. The said machine is fitted in position and attached by, unscrewing the wooden handle thereof suiiicientlyto allow it to be )ushed into position in the slot 10, after which the handle is screwed up, thus securely fixing the device in place.

Instead of providing a slot 79 a hole may be furnished in the projecting arm 7a. In this case the handle of the stamp'must be completely unscrewed, the shank passed through the hole and the handle afterward re-attached in order to fix the stamp in position. An upper arm 7 is provided at the back with a ring 9 in which engages a hook r formed with Or attached to the end of a wire, cable, rod or the like .9, which passes downward through a hole in the base plate and the bench to which the device is fixed, and is attached to a suitably located treadle.

The face of the stand, the recessed guides and the slide are all planed and polished so that when in operation the slide works freely and perfectly true up and down the face of the stand, thus insuring correct register.

The action of the device understood :On depressing slide with the stamp attached is brought down until the stamp comes into contact with the sheet of paper or other article to be stamped, leaving the desired impression thereon, the spiral spring it being at the same time compressed. On releasing the treadle the spiral spring pushes the armj upward causing the parts to resume their original positions ready for the action to be repeated.

The pile pf sheets of paper or the like to;

will be readily the treadle the being stamped so that like being apparatus may only then necessary to be stamped is fixed in the correct position under the stamp before commencing opera tions.

It will be obvious that both the hands of the operator are left free for the purpose of manipulating the paper, sheetsor the like the rate at which work can be done is much greater than is the case where the operation of stamping is being conducted solely by hand. Moreover, the stampdescends exactly in the same spot and perfectly clean, the paper or the kept in the exact position so that the register of the work being done is perfect, and a clear and clean impression results.

Although I have described and shown an apparatus adapted for fitting a single hand stamp thereto, it will be understood that the be modified to carry two or more stamps when required.

In the detail shown at Fig. 4 t is a plate formed with two slots at and carrying a small bolt and nut 91. In using this device the plate t is attached ,to the lower arm Zc by engaging the bolt and nut 'u with the slot 29 and tightening the same up. It is fasten the hand stamps in the slots at when it will be obvious that upon operating the mechanism both hand stamps will be caused to descend.

It is evident that by making the plate 2, of suitable length or shape any required number of hand stamps in any desired positions may be adapted to be operated by the machine.

ters Patent of the United States of America 1. An apparatus comprising in combination a treadle operated slide working in guideways on the face of a suitable standard attached by suitable means to a table, such slide being provided at one end with an arm furnished with a perforation working over a rod attached to the standard, :a compression spring around the said rod and between the said arm and the standard, another bent arm at the other .end of the slide provided with means to which an ordinary hand stamp can be readily attached substantially as described. c r 2. An apparatus comprising in .combina tion a treadle-operated slide working in guideways on the face of a suitable standard attached by suitable means to a table, such slide being provided at one end with an arm'fu'rnished with a perforation working over a rod attached to the standard, a compression spring around the said rod and between the said arm and the standard, another bent arm at the other end of the'sl-ide and means for attaching the plate, said plate being adapted to carry a plurality of hand stamps substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.
